In this study I made an analysis on the background of creating of Minimal Art and thought of its artists during 1950~1960 and their works. Starting from the early Modernism that tried to depict the life of farmers and laborers in the chaos of war and viewing the art as the tools describing the life itself, minimal art took its root as furniture in ordinary life passing through the era of Surrealism and Dadaism. In 20th century, furniture designers were trying to seek new trend of modern furniture in the perspective of balance and immaculateness while excluding emotion and overall feeling through minimalism. These efforts result in the introduction of immaculateness and refinement in furniture design. Hence, this study is to represent a new trend of furniture design utilizing the margin of furniture in complex lives through formative characteristics that minimal art beholds.

The optimal design was performed for the bridge superstructure composed of steel box girders and concrete deck considering life cycle cost. The service life of the superstructure was estimated, after load carry capacity curves for steel girder and concrete deck were derived on the basis of condition grade curves and maintenance histories. The object function was determined as life cycle cost, including initial cost, total maintenance cost, disposal cost and user cost, for a period of the estimated service life. The optimal design of the superstructure was performed for the various service lifes. The annual costs were used to compare calculated results and to get the most economical design. Also this paper presents reasonable idea for the use of user cost with uncertainty.

The purpose of this study is to analysis web sites which relate to housing environment on Internet and to suggest guidelines which are needed in digital life. Data are from key words in 53 web sites searched by housing environmental word such as people, living, town and so on. The results of this study were as follow: The web sites are divided into e-housing community, e-housing management, e-housing workplace and e-housing design. These are the digital life of new type. E-housing community sites make new wired community cross time and space. E -housing management sites provide the useful information of housing environment. E-housing workplace. sites enable us to work in cyberspace and e-housing design sites relate to consulting interior design. The web life style on Internet is common and makes many changes happen in house life and environment.

The purpose of this study was to investigate the relationship between lifestyle and the evaluative criteria of the Korean traditional costume, Hanbok and saenghwal hanbok. The questionnaires were administered to 291(men:.102,Women:189) university students in Seoul. Data were analysed by factor analysis, correlation coefficient, t-test. The results were as follows : 1) Factor analysis was used to determine the dimensions of the evaluative criteria of Hanbok, Saenghwal Hanbok and life style characteristics. The evaluative criteria dimensions were found to be different according to Hanbok. Saenghwal Hanbok. 2) In Hanbok, evaluative criteria were classified into comfort & easy care, prestige, design, fashion, suitability to yourself. 3) In Saenghwal Hanbok. evaluative criteria were classified into prestige, ease of care, design., appropriateness, brand. 4) The life style characteristics were classified into independence, activism. conservatism, and materialism. 5) There were the significant relationships between life style factor and clothing evaluative criteria. Especially for design in Hanbok and Saenghwal Hanbok was negative relationship with conservatism and positive relationship with activism. materialism. and Independence.

This paper presents a combinatorial method to compute the solutions of optimization problem. The present hybrid algorithm is the synthesis of an artificial life algorithm and the random tabu search method. The hybrid algorithm is not only faster than the conventional artificial life algorithm, but also gives a more accurate solution. In addition, this algorithm can find all global optimum solutions. And the enhanced artificial life algorithm is applied to optimum design of high-speed, short journal bearings and the usefuless is verified through this example.

Environmental Product Life Cycle Management is an activity for defining and describing the product, process or activity environmentally. Especially, the main responsibility for the environmental impact of products lies in the design phase of product. Designers cany a heavy responsibility to determine technical, economic and ecological properties of the product. So in order to help designers, structured understanding and application of treating large amount of data and infonnation should be considered. This paper presents a methodological approach for decision supporting to build Product Life Cycle Management system and show a set of database modeling. Additionally, a key issue for databases is the quality of the provided information.

The fatigue crack propagation is stochastic in nature, because the variables affecting the fatigue behavior are random and have uncertainty. Therefore, the fatigue life prediction is critical for the design and the maintenance of many structural components. In this study, fatigue experiments are conducted on the specimens of magnesium alloy AZ31 under various conditions such as thickness of specimen, the load ratio and the loading condition. The probability distribution fit to the fatigue failure life are investigated through a probability plot paper by these conditions. The probabilities of failure at various conditions are also estimated. The fatigue design life is predicted by using the Weibull distribution.
